Vaporizing Foil Actuator: Welding by Collision of Dissimilar Metals
Vaporizing Foil Actuator can be used for launching sheet metal of various thicknesses to velocities ranging from 300 m/s to 1 km/s. The oblique collision of this flyer sheet with another metallic part can lead to an impact weld. In this clip the VFAW process is shown for welding Aluminium with Steel.
